A slider is installed on the top, the upper end of the slider is connected with the lower end of the movable terminal, and the slider is connected with an external mechanical device; the magnet inside the movable terminal adopts a "halbach" magnet array.

Description

technical field [0001] The invention relates to the technical field of micro-displacement sensors, in particular to a magnetostrictive micro-displacement meter. Background technique [0002] With the development of modern information industry technology, the application range of displacement sensors is becoming wider and wider. Industrial control not only has more requirements for the measurement of large displacements, but also increases the measurement of micro displacements. In terms of micro-displacement measurement, there are many kinds of displacement sensors realized by different principles, such as capacitive, inductive, radar, ultrasonic, Doppler laser and so on. The principles on which it is based mainly include magnetic effect, capacitive effect, photoelectric effect, electromagnetic radiation effect, and mechanical effect. Although these micro-displacement sensors have been widely used in industry, they have quite a lot of shortcomings. Among them, the capaciti...
